CARBOY CAP CONSTRUCTION F iled Sept. 5, 1936 INVENTOR. fie fer /Ve /5o/7 Wis/W ATTORNEY.

Patented Nov. 30, 1937 CARBO-Y CAP CONSTRUCTION Peter Nelson, San Francisco, Calif; assignor to Staufier Chemicalv Company, a. corporation of California Application September 5, 1936, Serial No. 995580 Claims. -(c1. zit-56) r This invention relates to improvements in the construction of carboy casings, and, more particularly, to a device for connecting the casing cap to the main carboy casing.

V In Patent No. 1,885,534, of November 1, 1932, assigned to the assignee of this application, there is disclosed a successful carboy cap construction in which the cap is mounted by means of a hinged structure upon the top of the carboy casing. This structure represented a successful advancein the art. However, time has proven that the construction there disclosed was subject to objection. The first of these was that the construction did not permit of close packing of the carboys.

the carboys are ordinarily filled with heavy chemicals, and since the transportation cost of heavy chemicals is a vital factor in their sale, it is apparent that this is a serious objection, because it is to the advantage of the shipper of the 2 chemicals to pack as many as possible into a freight car. Another disadvantage is that the hinge end piece construction utilized as the cap lock depended upon the use of two hinge pins. These pins sometimes split the wooden end piece 25 or became bent so that the end piece did not hinge well and the cap' could not be readily secured.

It is in general the object of the present invention to improve upon carboy casings, particularly 30 the cap construction thereof, to the end that the casing may be repeatedly used.

Another object of the present invention is to improve carboy casing cap mountings to the end that while a removable carboy casing cap is pro- 35 vided, adequate means are available for securing the cap in position so that the protection of the Figures 3 and 4 are respectively figures taken 50 along the lines 3-3 and 44 of Figure 2.

Figure 5 is a schematic view illustrating how the carboy casings of the present invention can be readily stacked.

Carboys are usually glass vessels. Because of 55 the comparative fragile nature of these, they are Since usually packed in a wooden casing. In the drawing I have indicated a carboy l l as enclosed in the generally cubical wooden casing [2. The carboy includes a neck l3 which extends beyond the limits of the casing so that contents of the carboy can be readily removed. To provide a top for the carboy casing-in accordance with this invention, wooden strips! and Bare extended across the top of the casing and are secured thereto. These strips areparallel to each other and are 6 secured upon opposite sides of the casing. A like parallel pair of strips l1 and [8 are extended along the other sides of the casing on top of strips l4 and Hi. The sets of parallel strips .Mj-IS are cut out toprovide a round opening for the 15 neck 13 of the carboy, the neckcontinuing beyond the strips. 7. a

A cap structure is provided for mounting upon the carboycasing'toprotect the neck l3. This I cap structure, indicated generally by numeral I9, 0 is made up of two members in angular abutment. These members are indicated by numerals 2| and 22, the two members being tied together by side pieces 23' in "their angular abutting relationship. The 'distancebetween the non-abutting edges of 25 the members 2! rests upon members l4 and 16, while the si'depiec'es 23 rest upon side members 24.- It is to be noted that side pieces 23 are spaced from the'ends of the angularly positioned mem bers 2| so that the members 24 fit in between the r side pieces andlthe strips l1 and I8. Itis also to be notedthat members 241 are of thesa me width as side pieces 23 so that, as appears in Figure 5, carboys' can be stacked immediately between each cap structure. Thus carboy 26 is positioned upon carboys 27 and 28 immediately against the cap structures l9 on both of the bottom carboys.

.Means areprovided for locking the cap structure in position upon strips l4 and Hi. This lockn lm a i inc u ese oode b oek secu to strip 16 and having an angular face 32 thereon adapted to receive'and abut against the member 22 of the cap structure I9. The block member 3! provides an end closure for one side of the frame formed by strip l1, strip- I8 and block 2!; An end closure 33 is provided for the other opening in the frame, this end closure including beveled edges 34 slidable between the angular faces 36 formed on strips l1 and I8. Recesses 3'! are formed in the angular faces to receive dowel pins 38 carried by the end closure 33, movement of the end closure being limited by the pins 38 sliding in the slots 31. A latch '39 is mounted the end closure 33 is moved toward the side of the carboy casing so that the cap can be readily inserted to abut against end closure 3|. The end closure 33 is then slid in toabut the cap, and a latch 39 placed in looking position.

The foregoing carboy casing cap and the means for connecting it provides a very simple and effective structure. While I have disclosed the present preferred form of the invention, it is to be understood that various changes therein can be made by thoseskilled in the art without departing from the spirit of the invention as defined in the appended claims.

I claim:

1. In combination, a carboy casing having a top thereon through which projects a carboy neck, a cap for said neck, including two angularly positioned members secured together with an end of each member in angular abutment with an end of the other member, a pair of strips extending across said top to cover said top and along each side of said cap, an end closure secured to said top and abutting one of said cap members and positioned between said strips to cover said top, and another end closure slidable on said top and between said strip members to latch and release said cap and cover said top, said strip members extending over a portion of said slidable closure on opposite sides thereof to restrict movement of said slidable closure to a sliding movement between said strip members parallel to the plane of said top.

2. In combination, a carboy casing, a top thereon having an opening therein for passage of a carboy neck, a cap including two opposite angularly positioned members resting on said top for covering said neck, side members positioned on said top on opposite sides of said cap, another member positioned between said side members and extending over one of said angularly positioned cap members, a closure member slidable between and along said side members in the plane of said side members from a position in which said member extends over the other one of said cap members to a position in which said cap member is free, and a pin extending between an adjacent side of one of said side members and said slidable closure member into a cooperating slot in one of said side members to limit sliding movement of said closure member relative to said side members 3. In combination, a carboy casing, a top theresaid side members, said side members extending beyond said cap at least on one side thereof, adjacent extending faces of said side members being angularly formed to retain said slidable closure member, and a pin and slot connection between said closure member and at least one member on said top to limit the length of sliding movement of said closure member on said top.

4. In combination, a carboy casing, a top thereon having an opening therein for passage of a carboy neck, a cap for said neck including two opposite angularly positioned members resting on said top in neck covering position, side members positioned on said top on opposite sides of said cap, another member positioned between said side members and extending over one of said angularly positioned cap members, a closure member slidable between said side members and parallel to the plane of said top and the plane of said side members, said side members extending beyond said cap at least on one side thereof, being beveled toward each other, said slidable member having beveled faces on opposite sides thereof to cooperate with beveled faces on said side members to limit movement of said slidable member to a sliding movement coplanar with said top'and parallel thereto, and a pin and slot connection between said closure member and at least onemember on said top to limit the length of sliding movement of said closure member on said top. 7

5. In combination, a carboy casing, a top thereon having an opening therein for passage of a carboy neck, a cap for said neck including two opposite angularly positioned members resting on said top in neck covering position, side members positioned on said top on opposite sides of said cap, another member positioned between said side members and extending over one of said angularly positioned cap members, a closure member slidable between said side members and parallel to the plane of said top and the plane of said side members, said side members extending beyond said cap at least on one side thereof, and a pin extending from opposite sides of said slidable member into a cooperating slot formed in each extending side member to restrict movement of said slidable member to a sliding movement on said top in a plane parallel to that of said top.
